Re: Could not wrap a PopupPanel as a Composite!
It seems the PopupPanel will try to remove itself from its parent each
time of showing. The parent in this case is a composite which does not
implement HasWidgets, hence the exception.
Is this my misuse of PopupPanel or a GWT bug?

passing all gwt modules' rpc requests through a single servlet.
Hi,
My app is using multiple gwt modules and I want to do some set up so that no
change to web.xml is required whenever I add or remove a gwt module.
I replaced
@RemoteServiceRelativePath("greet")
by
@RemoteServiceRelativePath("../greet/")
so that all rpc requests from all the gwt modules pass through a single
servlet mapped to ../greet/* , say RPCService. Now I want to forward the
request from RPCService to corresponding ServiceImpl servlet based on . How do I do that ? I tried creating new instance to
ServiceImpl class and calling doPost() method, it threw
NullPointerException.
Thanks.

Styling of TabLayoutPanel tabs
Hi,
I have noticed since 2.0.2 that there seems to now be changes to the
styling applied to the TabLayoutPanel tabs.
Before I 2.0.2 I found that the default TabLayoutPanel had effectively
no styling (Firefox on Linux) and now there is a distinct background
colour for the selected tab, the unseleted tabs and a border around
the area below the tabs. Before the update I was styling the widgets
I added to the tabs (Labels) to give them the appearance I wanted when
selected/unselected.
I have been using firebug to have a look, and there seems to be a
class called "gwt-TabLayoutPanelTab gwt-TabLayoutPanelTab-selected"
that gets applied to the selected tab, and "gwt-TabLayoutPanelTab" (as
per the JavaDoc) for the unselected ones. (Firebug also says the
styling is coming from a file called chrome.css, but I am using
Firefox - I assume chrome.css is meant to refer to the appearance not
the browser?)
If I try and have in my style sheet the following to override it, it
does not work:
.gwt-TabLayoutPanel .gwt-TabLayoutPanelTab .gwt-TabLayoutPanelTab-
selected
{
background: red;
}
What am I doing wrong? Or, what is the best way to style the tabs?
Thanks,
Richard

Re: tomcat and apache problem
have you looked mod_rewrite ( http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html ) ? doesn't it help you? Why you need that the client side runs on apache httpd and not in a tomcat? do you have shared resources? if not, maybe you can let tomcat serve the client side also and, if you need performance, look at APR for tomcat ( http://tomcat.apache.org/tomcat-6.0-doc/apr.html ) On Sat, Feb 20, 2010 at 11:21 PM, dablack wrote: > Sorry to lead you on a wild goose chase.

Re: tomcat and apache problem
Sorry to lead you on a wild goose chase. I guess you will have to use the Apache mod_proxy_http module with the Tomcat NIO connector using the http protocol after all. I don't have any experience with the mod_proxy_http module at all so not really anything I can help you with. Good luck.

Re: tomcat and apache problem
I borrowed that connector configuration from a website I came across. I'm not sure why port=0 either. If I put more research into the NIO connector I could probably find out. Why don't you try adding the lines, enableLookups="false" scheme="http" to the NIO connector configuration in the server.xml file that I gave you earlier. As far as accessing the ajp service using http://localhost:8009/servlet, that will not work. Your browser uses the http protocol and the 8009 port is being serviced by the ajp protocol. You should still have your connector using the http protocol configured to listen on port 8081. Hopefully the scheme line above will help the NIO connector communicate back to Apache.

The module that you are telling is mod_jk and I cant use it because dont support NIO or I cant to do work.

Re: XHTML does not work?
That is pretty curious that the svg would load just because you have .xhtml as the file extension instead of .html, I have never used svg so this may very well be true and I'm showing my ignorance. About the validator, it's not the Holy Grail, code validation is very handy and a good discipline to keep, but sometimes you just can't make your code validate simply because you are using a modern spec that is unsupported or some browser specific feature. I see http://jwatt.org/svg/demos/xhtml-with-inline-svg.xhtml does have .xhtml on the end. Hmm. Well, stick with your .xhtml extension, and live with the fact that GWT's plugin will not offer you the convenient link? What you could do is just manually type the "production mode" link into your browser and then bookmark that... oh, having said that, perhaps the production mode browser plugin will not accept non-html extensions? Is the SVG something that GWT interacts with? On Feb 21, 2:56 am, markww wrote: > Hmm ok I see what you're saying.

Re: tomcat and apache problem
So basically you are trying to serve up 2 things. An app from Tomcat and some other web content from Apache server? Firstly, can't the other content be served from Tomcat too? That way you could just stop your Apache server from running, then configure Tomcat to load up on port 80 (default for http) and that way no one will every know they're hitting a Tomcat server. Or, there is an Apache server module, I forgot the name, but is allows you to specify that any normal request goes to the http server and then any request at /j/* gets pushed along to the Tomcat server. I'm hazy on the details but have seen it working before and I don't think it's using a proxy in the way you are. Could work?

Re: XHTML does not work?
Hmm ok I see what you're saying. I'm trying to include an element in my document. If I use the xhtml doc type template you linked to, I get it validated 100% in that validator you mentioned. Now I try adding a simple svg element and it failes. When I add my stuff to it, the validation fails. But I'm adding it as specified from the mozilla page on svg: http://jwatt.org/svg/demos/xhtml-with-inline-svg.xhtml when I leave this document as .html, no svg elements are rendered. When switching to .xhtml, then the browsers render it. I know this out of scope of GWT, just throwing it out there! Thanks for your help! On Feb 20, 3:35 pm, Paul S wrote: > Oh yeah you're right.

Re: XHTML does not work?
Oh yeah you're right. GWT development mode just simply scans the war folder for anything ending in .html and then offers those options to you "for your convenience". So 2 things to say here, 1. you are not limited to these URLs, you can type anything in your browser 2. GWT plugin just isn't seeing your .xhtml file, doesn't mean it's not there. However, to make everyone happy I'd recommend you change your .xhtml back to .html and then fix up the doctype to be XHTML. Honestly, that's all that counts, not the file extension. In fact try this: 1. run your app 2. right click and view source 3. copy your (x)html source code 4. visit http://validator.w3.org and click the Validate by Direct Input tab 5. paste your source code into there and click validate.

Re: XHTML does not work?
Hi Paul, Yes I set the path in web.xml, so it doesn't have any problem with that, it looks like when I try to run my project as a web app, I get the usual startup sequence, but no URL is provided for me when launch is complete. When I run a project using a .html file, I see this appear in the console: "For your convenience, here are some URLs that you may wish to view in development mode. Simply copy/paste a URL below into any suported browser." and normally the url is shown right there, but when using xhtml, no url is shown, that area is just empty. If I run a normal project, I can copy the url, then change it to point to my other project's xhtml file, and it is shown by the browser, but no javascript is executed. I am using Safari so it should be able to handle xhtml documents. I also updated the doc type via the url you had provided. This should be working?

Re: custom runtime exception got translated to StatusCodeException
I'm not sure about this one, but basically I do know that the GWT RPC
mechanism needs to know if your RPC services are planning on throwing
an exception. In my code I have the following:
public interface UserService extends RemoteService {
void save(User user) throws ServerSideException;
}
If I don't specify throws ServerSideException then I get "Call failed
on the server; check server logs", if I do add throws
ServerSideException I get control of the exception and I can give it a
meaningful message. I'm not sure that this is exactly what you are
facing though?

Re: XHTML does not work?
Switching to XHTML is about changing the doctype of the page, not the file extension. See this: http://www.w3.org/QA/2002/04/valid-dtd-list.html When you say you have updated the references, where? Are you getting something like: HTTP ERROR: 404 NOT_FOUND RequestURI=/index.html Powered by Jetty:// If so then you need to tell browser to hit your new URL. Also go into web.xml and change the default welcome page URL. On Feb 21, 12:33 am, markww wrote: > Hi, > > I want to use an XHTML file instead of an HTML file as the entry page > for my project.

Events (like Click) not firing when using UiBuilder? SOLVED
I started playing with UiBuilder this evening and I love it, thanks
Google!
I was working through the examples on
http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Overview
In the third code block down we see this:
HelloWorld helloWorld = new HelloWorld();
Document.get().getBody().appendChild(helloWorld.getElement());
... which works fine.
Later there is an example with a button that you can click and
apparently the event handling is magically done like this:
@UiHandler("button")
void handleClick(ClickEvent e) {
Window.alert("Hello, AJAX");
}
Clicking the button does nothing! It had me stumped for a while. I
found a few comments in the group saying it wasn't working. Then I
remembered that GWT has a "different" way of handling events other
than hooking onto raw elements, so of course this won't work:
Document.get().getBody().appendChild(helloWorld.getElement());
The solution is to use:
RootPanel.get().add(helloWorld);
Obvious now!

Re: tomcat and apache problem
Fran, I'm really not an expert on setting up the connection between Apache and Tomcat but I believe that the connections only operate in two protocols: http or ajp. NIO is a Tomcat connector that can communicate in either http or ajp. Because of that, I don't see any reason that the Apache mod_jk connector module couldn't communicate with the NIO connector. Since I don't use an NIO connector I could be wrong, but that is the way I see it. As a starting point, try these configurations: server.xml (You seem to want to use port 8081 which should be fine, but the standard ajp port is 8009. However, I wouldn't put it on port 8081 if you are already using that port for another protocol such as http.) httpd.conf LoadModule jk_module modules/mod_jk.so JkWorkersFile conf/workers.properties JkLogFile /var/log/httpd/mod_jk.log JkLogLevel info JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories JkRequestLogFormat "%w %V %T" JkMount /*.svc ajp13 (For the JkMount I use *.svc because I use the svc extension for my GWT service target to differentiate service points from other files.) (For example, in my web.xml file I will map my service something like this to use the svc extension: MyService com.mysite.server.MyServiceImpl MyService /MyService.svc And in my GWT code I create my service target like this: target.setServiceEntryPoint( GWT.getModuleBaseURL() + "MyService.svc" ); I did this because I had troubles with the 'JkMount /* ajp13' entry, but when I used /*.svc the problems cleared up.) workers.properties workers.tomcat_home=/usr/tomcat/apache-tomcat-6.0.16 workers.java_home=/usr/java/jdk1.6.0_06 worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp13.type=ajp13 worker.ajp13.lbfactor=1 worker.loadbalancer.type=lb worker.loadbalancer.balance_workers=ajp13 (Of course, match the ajp port in the workers.property file to the port you define in the server.xml file. Also, if your Tomcat is not on the same server as your Apache you will need to change the localhost host entry to the correct host URL.) I hope this helps.

To give you an idea what we're looking at, there were over 180 issues submitted post 2.0. Many of them without a sufficient repro case, or simply support related questions. On top of that, we have a backlog of roughly 600 internal issues that have been reported by Googlers that we are trying to address. We've managed to triage 380 of those issues, and should have the internal issue tracker cleaned up shortly. Once we have that out of the way we're moving to the external issue tracker. We talked the internal issue tracker first because, for most issues, we know more of the history and therefore it's easy to triage. Net, net -- there's a large amount of information that we need to clean up and organize. It's going to take some time. The effort a few months ago was a broad swipe at removing items that are no longer an issue. I still have starred issues from 2006 like: > > http://code.google.com/p/google-web-toolkit/issues/detail?id=374 > > which is still in accepted status and has even been commented that it > was still present in 2.0.0-m2, but still no resolution. > "Accepted" is admittedly a bit vague.

How to add unit test to GWT/AppEngine project created by Eclipse
Hi, How do I add easily unit tests to a GWT/AppEngine project that I already created a while ago. If I start from scratch I know I can use webAppCreator like described here [1] but I already have my project. I also noticed that when I create a New Web Application Project in Eclipse that a test directory is created but what do I do to make tests run that are in there.

Re: Slider Panel like in maps?
you can find Collapsible panel implemented in GWT here: http://code.google.com/p/gwt-incubator-1-5-wiki/wiki/CollapsiblePanel or in GXT just set panel.setCollapsible(true); to the panel.

Chris, Thanks for the link and great content.

Re: tomcat and apache problem
Should be due to protocol. My messenger seems that need NIO protocol but if I put the NIO protocol MOD_JK cant conect apache with tomcat If I use this tomcat config, mod_jk cant conect apache with tomcat. If I use the last tomcat config, tomcat cant execute the servlet.

Re: tomcat and apache problem
I am configuring mod_jk For tomat, in server.xml : For apache, in httpd.conf : JkWorkersFile "/etc/httpd/conf/workers.properties" JkLogFile "/etc/httpd/logs/mod_jk.log" JkLogLevel warn JkMount /msn/* worker1 The result is that the url: http://localhost/msn/Messenger.html works, but this html conects to servelet that not work.

Re: Using FocusWidget.addClickHandler for GWT 2.0 Hyperlink (ClickHandler deprecated)
Hi Tapas- Check out this issue for the reasoning behind the deprecation of Hyperlink.addClickHandler: http://code.google.com/p/google-web-toolkit/issues/detail?id=1960 from tamplinjohn's comment on that thread: "I also think that allowing click listeners/handlers on Hyperlink is part of the reason for the confusion -- if its goal is to manipulate the history state, there isn't any reason for adding a listener on the click, but you should instead add a history listener so that function works the same way whether activated by a click, a back button, or loading from a bookmark. If for some reason you do really need a click handler, then it can still be done by using Anchor and calling History.newItem from its listener."

Could not wrap a PopupPanel as a Composite!
Hi,
I always get the exception: "java.lang.IllegalStateException: This
widget's parent does not implement HasWidgets" while trying to use a
Composite which wraps a PopupPanel.
A simple example:
// The main application window
public class AppWindow extends Composite {
private final PopupPanel panel = new PopupPanel(true);
public AppWindow() {
initWidget(panel);
}
public void show() {
panel.setSize("300px", "300px");
panel.add(new Label("Application Window"));
panel.show();
}
}
// A button to trigger the application window
public class AppButton extends Composite {
private final Button button = new Button("App");
private final AppWindow window;
public AppButton(AppWindow window) {
this.window = window;
button.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
AppButton.this.window.show();
}
});
initWidget(button);
}
}
// Entry
public class Ping implements EntryPoint {
@Override
public void onModuleLoad() {
AppWindow window = new AppWindow();
AppButton button = new AppButton(window);
RootPanel.get().add(button);
}
}
Now click the button I always get the expected exception :) . It's the
same if the trigger is done via an event bus (i.e., the AppButton
fires an event, the AppWindow catchs the event and show it self).
Note that it's ok if AppWindow does NOT extend Composite.
Could someone explain please?
The stack trace:
00:29:42.628 [ERROR] [ping] Uncaught exception escaped
java.lang.IllegalStateException: This widget's parent does not
implement HasWidgets

Re: Some question about Serialization tricks...
That doesn't fully address the entire question, though. Aside from the potential gotchas about using java.io.Serializable, the source files are still in a separate project, which is easy to imagine in a larger modular project. I've heard of people including the source when bundling their jars, but I wasn't able to get GWT to find the source there myself. My imperfect solution to the problem was to write a code generator that uses reflection on specified classes to generate both IsSerializable DTOs and utility classes for convering between the two. It turned out to be a bigger project than I wanted it to be, even for the limited cases I had, and it needs a complete rewrite. However, I'd be happy to share the ideas and what code I have if anyone else is interested in contributing. I think this is a significant inconvenience for GWT and would like to find a good long-term solution for it. -Brian On Feb 1, 10:22 am, Paul Robinson wrote: > You don't *have* to use IsSerializable.

Re: Help with GWT FlowPanel and other Panel Styles!
You need to apply the CSS to the children of the FlowPanel (i.e. what you are adding to the panel) rather than the FlowPanel itself. Out of interest, are you using UiBinder or not? Any particular reason you don't want to use HorizontalPanel?
